Colorful Language is an extension for any CoreRPG-based ruleset that adds the ability to configure chat fonts, both for general messages as well as individually for each character and NPC. General font configuration may be accessed by the GM from the chat window radial menu. Character fonts may be configured from the radial menu of the chat icon on the character/NPC sheet.

Check it out and please let me know if you have any comments or concerns.
Hope it helps!

If you wish to buy me a coffee, I would be extremely grateful. Though please don't feel any pressure or obligation to do so!
